TORRANCE, CA — July 5, 2005 — LEDtronics introduces the SML5050RBG1K-TR
— a low profile, surface mount full-spectrum Red, Green and Blue
LED (RGB LED). These discrete LEDs provide excellent performance and
terrific visibility in a compact size of only 5.5mm x 5.5mm. The red,
green and blue diodes emit high-intensity light in a viewing angle of
120°. The red diode's wavelength varies between a minimum of 620nm and a
maximum 630nm. The wavelength of the green diode is between a minimum of
520nm and a maximum of 535nm. Blue operates between 460nm and 475nm.
Depending on the color, luminous intensities range from 150 mcd to 500 mcd
at 20 mA current. A water clear lens protects the diode array.

Use SML5050RGB LEDs with LEDtronics OptiLED Light Pipes to simplify the
spatial relationship between the PCB and remote indicator illumination
points. Light pipes channel all of the LED-generated light to the exact
location where the light is required. Compatibility with infrared and
vapor phase reflow soldering processes and pick-and-place automated
equipment make the Series SML5050RGB LEDs effective tools in cutting costs
in PCB assembly while maintaining product integrity. Series SML5050 LEDs
broaden the illumination options available for back lighting computer
panels, handheld instruments like PDAs, data- and tele-communication
status indicators, etc. Solid-state design renders LEDs impervious to
electrical and mechanical shock, vibration, frequent switching and
environmental extremes. With an average life span of 100,000-plus hours
(11 years), LEDs operate reliably year after year and are virtually
maintenance free.
